29; see text Toxicodendron is a genus of flowering plants in the sumac family, Anacardiaceae.
All members of the genus produce the skin-irritating oil urushiol, which can cause a severe allergic reaction.
Plants in the genus have pinnately compound, alternate leaves and whitish or grayish drupes.
[7] The common names come from similar appearances to other species that are not closely related and to the allergic response to the urushiol.
The sumac wax was a byproduct of traditional Japanese lacquer manufacture.
